   • Install necessary libraries (e.g., Python, TensorFlow, or PyTorch).
   • Use APIs like OpenAI’s GPT-4 for NLP capabilities.
2. Train the Model:
   • Feed the chatbot with sample conversations.
   • Use datasets like Cornell Movie Dialogues Corpus or create your own.
3. Integrate with Platforms:
   • Use APIs to connect your chatbot to platforms like Slack, WhatsApp, or your website.
